I don't know if this belongs here or in the Brew Session thread so I took a chance. This is not a feature request, it's something I can handle on my own and it's my Kentucky Common. It's a rather complex mash scenario in that I mash the 6-row and the flaked grains. I cap the sparge with the dark grains and add the molasses with 5 mins remaining in the boil. So, to calculate the mash water volumes, temperatures, salt and acid additions, I have to back out the dark grains and crystal in the water and mash calculators. Then add them back to get the boil gravity and sparge acidification to model my mash capping. Then add the molasses back to get the final gravity. I don't know that supporting complex scenarios like this is even possible or desirable in a general brewing software package like Brewer's Friend but it's something to think about.
